Not being able to die shouldn't be an issue here as no one hit by the explosions actually dies anyway. If they got hit by the blast they would have lost as per the rules, but both have special abilities to block the flames from the explosions (Kaguya's Robe of the Fire Rat & Mokou's fire manipulation magic), so since they never get hit they aren't eliminated. It's kind of cheap (just because the explosion doesn't actually damage them doesn't change the fact that they got hit), but them's the breaks in this doujin.
What's really weird is Komachi should be damn near invincible against anything that isn't an ambush since she can just manipulate the distance so that the explosions never reach her and Cirno! Why Chado didn't have her do this but had Cirno freezing bombs, Medicine using her posion (even though attacking your opponent directly is supposed to be against the rules), and Kaguya/Mokou using anti-flame stuff to escape elimination on a mere technicality is beyond me!

Balance issues.
Also, invinsibility tripped an obvious death-by-falling-block flag.
Rebirth of the Phoenix (Explosion has no effect)Aren't we the ultimate pairing?Though we have the worst relationship.Their own bomb has triggered other bombs setting off a chain explosion resulting in fireworks!Salamander Shield (Explosion has no effect)Ooh-What's this now! The Kaguya and Mokou pair is unscathed!How the hell can they be defeated like that!And the Komachi & Cirno pair retires here!!A fire pillar is coming!That's cheating!!!
